BRICK-PRESS.

SPECIFICATION forming part of Letters Patent No. 316,939, dated May 51885.

T Application filed January 5, 1885. (No model.)

To all whom it may concern."

Be it known that I, JOSEPH R. BownRs, of

Concord, in the county of Merrimac, State of New Hampshire, haveinvented a certain new and useful Improvement in Brick-Presses, of whichthe following is adescription sufficient- ]y full, clear, and exact toenable any person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a side elevation of my improved brick-press; Fig. 2, a topplan view of the same, and Fig. 3 a vertical longitudinal section.

Like letters of reference indicate corresponding parts in the differentfigures of the drawlngs.

My invention relates to that class of brickpresses which are employed infinishing or facingQthe brick; and it consists inanovel construction andarrangement of the parts, as hereinafter more fully set forth andclaimed, by which a more effective device of this character is producedthan is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the bed-piece or body of the machine,which is rectangular in form, and provided at one end with the legs B B,and near its opposite end with the trucks O G.

Projecting upwardly from the body A, and at either side thereof, abovethe leg B, there is a standard, D, carrying a friction-roller, E.

A standard, H, is disposed at .either side of the body A, nearly overthe axle of the trucks 0, and connecting these standardslthere is across head or bar, J.

Two standards, K, are arranged nearly midway between the standards H Dat the center of the machine, the last-named standards being connectedby the cross head or bar L. I

A main frame-work, rectangular in form and consisting of the side rails,M M, and end rails, N Q, is disposed on the upper portion of themachine, said frame-work resting on the friction-rollers E, and propersupports or ways (not shown) on the standards H K being adapted tomove'back and forth on said supports,

when reciprocated, as hereinafter described.

J ournaled in the upper portions of the standards K there is a toothedsegment,0, adapted to intermesh with a corresponding toothed segment, P,which is journaled at .10 near the end rail Q of said frame-work.

Projecting upwardly from the rails M, at either side of the machine,there is a standard, R, and journaled horizontally at m in the upperportion of these standards there is a rocker-shaft, S, provided with ashort arm, T, and lever U, arranged nearly at right angles with eachother on said shaft, a portion of the lever being represented as brokenoff.

An auxiliary frame-work consisting of the side rails, 12, and head-railw, is fitted to slide in proper ways 13 on the inner faces of the siderail, M, being rendered adjustable laterally by the set-screws t. I

A bar, Y, extends horizontally between the standards H H, and disposedthereon is a bedplate or table, Z.

A cap-plate or bar, G, is disposed between the standards H above thetable Z, being adapted to slide vertically between said standards, andrendered adjustable by the set-screws g.

A follower, h, is attached to the end rail N, and projectinghorizontally from either end of the head-rail w there is a bar, d, thesebars being arranged in parallelism and connected at their outer ends bythe cross-bar b, carrying the face-plate f.

The matrix in which the brick is pressed is formed by the bed-plate ortable Z, cap-plate or bar G, face-plate f, follower h, and standards H,or by vertical end pieces, (shown by the dotted lines k in Fig. 2,)which end pieces extend between the bar G and bed-plate Z, and areproperly backed or supported.

Attached to the shaft 1, on which the segment P is journaled, there is adownwardlyprojecting curved arm or kicker, n, adapted to engage astandard, F, at the end of the body A when said segment is depressed, as

shown in Fig. 1.

cent thesegmem tal and the lever U in a vertical position,with theface-plate f advanced to the outer opening of the matrix, as shown inFig. 1, the brick I is then placed on the bed-plate or table Z in 5front of the follower h and the lever U depressed to bring the partsinto the position shown in Fig. 3.

As the segments 0 P are raised by depressing the lever U, therectangular main frame- 1 work will be moved in the direction of thestandard F, causing the follower h to force the brick I into the matrixand push the face-plate f out of the matrix until the projections j onthe rails 11 strike the standards K or bar L, 15 thereby stopping theadvance of the auxiliary frame, after which the main frame-work,consisting of the rails M N Q, continues to advance for a short distanceas the lever U is further depressed, thereby forcing the follower hagainst the brick and the brick against the face-plate f in the matrix,and pressing or facing it in a manner which will be readily obviouswithout a more explicit description.

After the brick has been pressed as de- @scribed, the lever U iselevated, permitting the segments 0 P to drop by gravitation and bringthe curved arm 12 against the standard F, thereby kicking or forcing themain frame toward the standards H and withdrawing the follower h fromthe matrix, bringing the parts againinto their normal position, as shownat Fig. 1.

Projecting inwardly from the inner face of either rail M M there is astud or stop, s, and as the rectangular or main frame is pushed back bythe curved arm n, as shown in Fig. l, the studs 8 are brought intocontact with the side rails, '11, of the auxiliary frame, causing saidframe to advance, and the face-plate f to force the pressed. brick outof the matrix onto the table Z, from which it may be removed preparatoryto repeating the operation.

One of the side rails, M, is curved downwardly at the end nearest thestandard H, as shown at q, Fig. 3, thereby enabling the pressed brick tobe readily removed from the table by shipping them endwise therefrom,which can be done to better advantage than to lift them vertically.

From the foregoing it will be obvious that the pressure on the brick bywhich it is faced occurs after the auxiliary frame is stopped by thestandards K or bar L, at or about which time the parts have assumed theposition shown in Fig. 3.

\Vhen the lever U is depressed and the segments 0 P are elevated, thepitnien or links 7' approach the center of motion at of said lever,thereby in effect shortening the arm T and greatly increasing the powerof said lever, while at the same time the central axial lines of thesegments 0 P, continuing to approach a horizontal line drawn throughtheir pivotal supports, the power exerted through the medium of thesegments on the rectangular or main frame-work is greatly increased, thesegments approaching a horizontal position, and the arm T a verticalposition at the time when it is required to exert the greatest pressureon the brick.

The matrix may be increased or decreased in size, as desired, by raisingor lowering the cap-plate G and changing the follower h, faceplate f,and end pieces, k, in accordance with the size of the brick to bepressed. 75

The trucks enable the press to be readily removed from place to place asrequired, and serve in place of legs to support one end of the machine.

By disposing the matrix at the end of the machine opposite the lever Uthe insertion and removal of the brick are greatly facilitated and roomafforded for the proper operation of the other parts.

Having thus explained my invention, what I claim is- 1. In abrick-press, the combination, with a reciprocating frame or follower, ofa shaft pivoted to said reciprocating frame and traversing therewith, atoothed segment fixed to said shaft, a shaft supported in fixed bearingson the machine, a toothed segment attached to the last-named shaft andintermeshing with the segment on said traversing shaft, uprightstandards attached to the reciprocating frame, a rock-shaft supported insaid standards above said segments, a crank-arm on said rock-shaft, apitman connecting said crank-arm with one of said segments, and anactuating-lever attached to said rock-shaft, the said parts being 1:0arranged substantially as described, whereby the pitman is caused toapproach the center of motion of said rock-shaft when said segments areraised by the depression of said lever.

2. In a brick-press, the rocker-shaft S, provided with the lever U andarm T, in combination with the segments 0 P, pitman 1", standards K, anda sliding frame-work having the standards R R and carrying a follower,substantially as set forth.

3. In a brick-press, the curved arm n, in combination with the segmentP, standard F, and the sliding main frame-work, substantially asdescribed.

4. In a brick-press, the rail M, provided with the curve q, to enablethe brick to be removed from the table Z, substantially as described.
